High-purity reference materials for accurate residue analysis

Overview

Naphthalene is an organic compound with the chemical formula C₁₀H₈. It is the simplest polycyclic aromatic hydrocarbon and appears as a white crystalline solid with a characteristic odor detectable at very low concentrations. Naphthalene is primarily derived from coal tar and is used in various industrial applications.

Uses

Naphthalene is used mainly as a precursor to derivative chemicals. The largest use is in the industrial production of phthalic anhydride, which is an intermediate for making plasticizers and alkyd resins. It is also used as a fumigant, solvent, and in the production of various naphthalene derivatives such as naphthalenesulfonic acids, which are used in dyes, rubber processing chemicals, and pharmaceuticals.

Regulatory

In the United States, the Occupational Safety and Health Administration (OSHA) has set a permissible exposure limit for naphthalene at 10 ppm over an eight-hour time-weighted average. The National Institute for Occupational Safety and Health (NIOSH) recommends the same exposure limit and a short-term exposure limit at 15 ppm. Naphthalene is classified as a possible human carcinogen by the International Agency for Research on Cancer (IARC) and is listed under California's Proposition 65 as a chemical known to cause cancer.

Monitoring

Monitoring naphthalene levels in the environment and workplaces is crucial due to its potential health hazards. Analytical methods such as gas chromatography and mass spectrometry are commonly used for detecting and quantifying naphthalene in various matrices, including air, water, and soil.

Health Impact

Exposure to large amounts of naphthalene can damage or destroy red blood cells, leading to hemolytic anemia, especially in individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency. Symptoms of exposure include fatigue, lack of appetite, restlessness, and pale skin. Chronic exposure has been linked to cataracts and potential carcinogenic effects.

Environmental Impact

Naphthalene is a persistent environmental pollutant that can accumulate in the soil and water. It is toxic to aquatic life and can cause long-term adverse effects in the aquatic environment. Its volatility also contributes to air pollution.

Safety Measure

Handling naphthalene requires strict safety measures to prevent exposure. Personal protective equipment (PPE) such as gloves, goggles, and respirators should be used. Proper ventilation and adherence to occupational exposure limits are essential. In case of spills, containment and proper disposal procedures must be followed to minimize environmental contamination.
